優點:
wide aperture choice (1.8-22)
light weight
compact
use 52mm filter (cheaper filters)
缺點:
Construction 唔太實淨, 因為係plastic 鏡筒
對焦時鏡筒伸縮易入塵, 對焦環會轉
冇hood送 , 並只可用Screw in type hood
冇袋送
因冇built in motor, 用唔到m/a mode
45cm closiest focus 近D 好d
評價:
鏡片同filter距離太遠, 令到好容易出現內反射, 所以要用貴d嘅multi-coated filter, 或唔用
Chromatic aberration (紫邊) gone by f/2.8
